If you have to drive, use Parkos and park at a hotel and take their shuttle to the airport. Much cheaper than any closer airport parking and it is monitored by the hotel.

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

More than one hour detail with no explanation and no compensation

my husband's monitor did not work. there was a visibly ill family in my husband's row.

Comfortable seats, good service overall. The food could’ve been a little bit better. The boarding process was slightly chaotic and in fairness, not all of that is related to the performance of British Airways.

The chairs were a bit tight even though I had extra feet space…2nd plane didn’t have entertainment and even though they said there was free WiFi-I believe the free WiFi wasn’t accessible unless u had some account set up….which I didn’t figure out

On time. Comfortable sats. Clean aircraft. Friendly crew. Good food.

Naples airport not the best ! Boarding via coach to aircraft never the best. Staff and captains announcements good. Flight on time with soft landing. Ran out of sandwiches half way down the plane. !! Not impressed. 7/10 satisfaction overall

The seats are not comfortable if you are not tall.

The flight was cancelled and I was re-routed via an inconvenient routing proposed.

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

Firing with British airways leaves me feeling stressed and disappointed. They are substandard in so many aspects of airline travel.

Worst trans-Atlantic flight in years! The seats were incredibly tight, both in width and depth. The back selection was so cold, it was like traveling in a refrigerator. Although I had an entire row, the seat arms would not go up, so I could not take advantage of it to sleep. However, the crew was smiling and helpful and really seemed to enjoy their jobs. The food was the worst I have ever experienced on any flight. The PA system blasts announcements to the point of hurting my ears when using the audiovisual equipment. Not safe or sat. Also, I did not like the bait and switch tactic. I put in a search with one bag and the other flights had put that into their price, but BA did not and made me pay extra for it which would have made the price comparable to others. Also, even at check in there was no “choice” of seat, unless you paid extra for it even in the same row. No other airline I have been on does this. Once check in begins, normally, you can choose any unoccupied seat in your category. These tactics and the lack of comfort means I will never fly BA again.

An early flight and a bit confusing where to check in with British Airways; good we asked at the information counter the night before as we stayed overnight at the Sheraton on the departure level.
